What is CVE-2026-32117?
CVE-2026-32117 is a high-severity cross-site scripting vulnerability in ekacnet grafanacubism-panel, published on 11 Mar 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Official description
The grafanacubism-panel plugin allows use of cubism.js in Grafana. In 0.1.2 and earlier, the panel's zoom-link handler passes a dashboard-editor-supplied URL directly to window.location.assign() / window.open() with no scheme validation. An attacker with dashboard Editor privileges can set the link to a javascript: URI; when any Viewer drag-zooms on the panel, the payload executes in the Grafana origin.
